Details are scant, but Cartoon Network is getting two new cartoon series in 2013. One will be Rebecca Sugar's Steven Universe.
This is what's known so far about the upcoming show
"Sugar's Steven Universe is a coming-of-age story told from the
perspective of Steven, the youngest member of a team of magical
Guardians of the Universe."
I also wonder what might happen to the show if Natasha Allegri leaves if Puppycat and Bee gets picked up for YouTube series.
Rebecca's done some fan favorite episodes and come up with a lot of the songs within the show, hope to see more about the show as it gets closer to coming out.
